Be it known-that 1, WILLIAM citizen of the United States, and'residentot Rochester, in the. county of Monroe and State of New-York, have invented certain new and useful Improvements in Deep- Well Pumps, of which the followingasa specification."

The present inventionrel'ates todeep well a 1 b r h P je t s. .2 d p ndin t at? from, in this instance, tour in number,} two .f

pumpsand more particularly 'toftthe type employing an upper and aflloweii bucket working in opposite directions." f-Anobject of this invention is to provide a construe tionin'which the passageway' thro'ugh the pistons or buckets is'inc'reased toa maxi}v mum, while at the-same time" giving effective valve seats which have no tendenoyto leak. Another object of the invention is to efiectively support the pistons or buckets from points about the valves so 'th'at'only one: valvefseat' is required for each valve and the area otthe passageway through the bucket may be lncreased. 'Stillanotherob'-' ject of the invention is to provide a con-' struction inwhich the upper valve operates directly about" the rod of the lower piston p a portion: of a deep well pump constructed erating'mechanism not being shown and be- 1; a nd h Fig. 4 as an enlarged vertical section through the upper valve. 1 501 and has a packing relation withfsaid rod so that leakage between the rod and-the valve is nil; A still further obj ect-of the invention is -tofprov'ide for packing the pump against" surge betweenwthe rod carrying the lower buoket-or-piston and the hollow rod carryin;; the upper bucket or piston. r To these and other ends, theinvention consistsfof certain parts and combinations of-parts, au of whieh'will be hereinafter described, the novel featuresbeing pointed out in the appended claims.

This flexible packing with the convex seat 10? will therefore insure the seating of the valve. under all conditions. I I I 1 Movement of the upper piston or bucket is effected through a hollow piston rod 9A-v surrounding the piston rod l l'and connected with the bucket or piston 2. This connection, inthis instance, is effected by a coupling member 25 to one end of which the piston rod 24 is secured. The-other end.

of the coupling member connectswith an externally threaded boss '26 on a cage 27,

the latter having ring 28 at its lower end which is internally threaded and engages external threads on the piston or'bucke't 2 It will be seenthat the hollow piston rod upper bucket or piston 2 on the exteriorof the bucket. This arrangement permits the making of alarger passageway through the bucket2 and at the same time makes it pose a sible to use only one seat on the bucket for engagement by the valve 11?.

The valve 11? will moveto its seat by the pressure of the water above it, but this seating may be assisted by a helical spring 18?, which at its lower, end seats against the valve 11 andat its upper end seats against the cage about an annular projection 19. l I

It desirable to provide a packing about the piston .rod 14 to-prevent surge passing ing 80 is received to fit tightly into the hollow piston rod 2% and with this end in view the annular projection'19 is v provided'with a pocket 29in which'a packpiston rod 14:, a locking ring 31 securing the packing in the pocket. This packing is open at all times to the'pressure above the valveof the upper piston or bucket.

"From the foregoing it will be seen that there has been provided a piston or bucket which has a maximum water way both through the body ofthe piston and about the valve. possible slip on the lower valve is limited. to one imetal seat and this 24; connects with the about the without packing of any kind. The possible slip on the upper valve is limited to one unbroken metal seat and to a packing around a small polished rod carrying thelower pistonv Both valves have a tendency torotate, which makes them self-grinding and brings new parts of the seats in contact at each stroke, this being particularly valuable when the water being pumped contains valve has a pacl'ring about it carried by the cage ofthe upper piston. This increases the mechanical efficiency of the pump by decreasing the slippage of water from a surge 1 between the two piston rods, this being particularly valuable under heavy loads of pressure and producing a smoother pump operation Increased passageway through the pistons together with the springs'operating on the valves, makes it possibleto obtain a higher piston speed, a more rapid and positive closing of the valves, thus; obtaining a] larger quantity of water from a givensiZed piston and cylinder and longer life to the bistons; without attention.
